The 'Ch-Rho' symbol on our altar and tabernacle plinth in St Joseph's Church stands for the first letters of Christ in Greek.
In 1963 a Roman mosaic was discovered at Hinton St Mary near Sturminster Newton. It features perhaps the oldest image of Jesus in the world with this same 'Chi-Rho' symbol. Whilst this was commonly used to refer to Jesus, it nevertheless points to a remarkable continuity of art and faith in our country stretching back over 1600 years.
The pomegranates either side of Jesus' face are symbols of eternal life. Have a listen to this fascinating 13 minute BBC clip that tells you more. (Sadly and rather unbelievably the British museum recently broke most of the mosaic up. Perhaps we should ask for its safe return now to Dorset...)
